Temperatures soared past 100 degrees Saturday all the way to the Southern California coast. Several records were set. Heat will continue to dominate across the West this week. However, it will not just be limited to Southern California. Temperatures will be well above normal from Southern California northward to the Pacific Northwest much of this week. This is not good news for fire fighting efforts that are ongoing across much of the interior Northwest.

Temperatures in Portland should reach above 90 degrees on one or more occasions. Seattle will record high temperatures near 80 each day through Friday. Record high temperatures will be challenged in some areas through the end of the week.

Across interior areas, temperatures will also be soaring in cities such as Spokane, Wash., and Boise, Idaho. Highs will top 90 degrees at both locations this week, challenging records.

The building heat in the West is a response to a massive area of high pressure forming over the area. This high will in turn send a very strong trough into the East, causing the storminess and cool temperatures next week.

Longer-range signs point toward the high sticking around the Western states right into next weekend.

While the warm weather is welcome for folks wanting to get outside, poor air quality will put a damper on some outdoor plans.
